Systems and methods for timing mismatch calibration in distributed mimo using multiple sub-band measurements

Abstract

In one embodiment, a method includes determining an optimal number of resource block separation between pairs of measurements based on system settings of a distributed communication system, wherein the system settings specify one or more of a maximum tolerable calibration error or a required calibration accuracy, accessing transmission signals comprising at least a first transmission signal and a second transmission signal, accessing measurements using reference signals at multiple sub-frequency bands over a particular frequency band, wherein the measurements comprise at least a first pair of measurements and a second pair of measurements, wherein the first and second pairs of measurements are separated by the optimal number of resource block separation, determining a timing mismatch between the first and second transmission signals based on the optimal number of resource block separation, and generating an integrated transmission signal based on the first and second transmission signals and the timing mismatch.
